The DBH 8319 is a radial shaft seal built around a rotating shaft. It keeps lubricant where it belongs and blocks dust, water and other particles from getting in. You will find this type of seal in gearboxes, pumps, electric motors and similar industrial equipment, where the shaft turns inside a fixed housing. With a 140 mm shaft, a 165 mm housing bore and a height of 13.00/16.50 mm, it fits demanding duty.

Read the code by its numbers: shaft 140 mm, housing 165 mm, width 13.00/16.50 mm. The A 090 design is a single lip with a spring, in an elastomer that resists oils and greases. Because the height is stepped, the seal anchors better in the bore and tolerates minor imperfections in the cavity. It works as a direct replacement wherever reliable sealing is needed under continuous rotation.

Typical installations include gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. You will also see it on agricultural, road and process machinery, where the shaft sees vibration and temperature swings. The radial layout handles moderate peripheral speeds and low pressures, as long as the shaft is ground and the housing roughness is right.

Before fitting, inspect the shaft for burrs or marks and make sure the bore is clean and undistorted. Put compatible grease on the lip, then slide the seal in. The 13.00/16.50 mm height lets it seat against a shoulder, so check that the support face sits square to the shaft. In dirty service, a protective seal or better external sealing is worth considering.
